OCR

OCR Tables and Parse the Output 

Pros: OCR software frequently misidentifies 4/A, 8/B, 0/O, and other characters. The program created by Prof. Dell could address these issues.

Cons: My experience with the PDF version of the Japanese census shows that the programming could extract half of the data without needing to double-check it manually.
